This is a commercial outfit that offers online boating courses for quite a few of the U.S. states and Canada. Many areas require some type of boater safety course or the like before younger people can operate watercraft by themselves. This company offers some interesting looking courses and tests. I can’t vouch for their legal acceptability (or their quality for that matter), but it might be worth checking out.
